1、 Curing method

1. Temperature: it can withstand low temperature and high temperature. The minimum temperature can reach minus 25 degrees. Therefore, it is often used as a greening plant in the north

2. When the water content of the plant is not 60%, it can be watered twice a week. Generally, the water content of the plant can be prolonged when the temperature is not 60%

3. Fertilization: after the long roots of seedlings are unearthed, nitrogen fertilizer can be applied to them, which can promote the growth of seedlings. In autumn, phosphorus and potassium fertilizer should be used to promote the lignification of plants and help plants increase their ability to resist the cold

4. Illumination: the illumination time given to it every day should be more than five hours. It needs appropriate shade in summer. It should receive all day sunshine in autumn and winter to meet the illumination time and intensity

2、 Breeding skills

1. Breeding: it can be sown in autumn. First of all, we should choose a place with relatively high terrain and leeward and sunny, and then adjust the land. It's best to be fine and flat. Mix the base fertilizer inside and sow in the way of drill sowing. After sowing, cover it with a layer of soil, water it once, and wait for it to germinate

2. Pruning: in winter and spring, choose healthy branches and cut them short. In summer, prune the redundant branches and remove the newly grown branches and buds, so as to concentrate nutrients

3、 Problem diagnosis

1. Insect pests: Luan tree is easy to be infected with aphids. In serious cases, the branches and leaves of the whole tree will be covered with aphids, and the insects will eat the branches and leaves of the plant, causing irreversible impact on the growth of the plant. In this case, the plant needs to be sprayed with aphidijing. In addition to the first time, we should also protect beneficial insects such as seven star ladybugs, which can also eliminate insect pests

2. Pathological changes: the plant is easy to be infected with glue flow disease. After the plant is infected, the infected part will swell and the epidermis will become moist. In the later stage, it will crack and retain glue. In case of disease, use carbendazim solution for spraying

4、 Other issues

1. Toxicity: it has no poison. Generally, landscape plants have no poison. It is a good choice whether as greening plants or family potted plants

2. Whether it is suitable for indoor breeding: if it is a potted Luan tree, it can be cultured indoors. Outdoor landscape trees can't, because they are too big to meet the requirements of indoor breeding
